(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

  • Despite their advanced capabilities, heavy-duty sewing machines are designed to be user-friendly. Many manufacturers have made strides in making these machines accessible to both amateurs and seasoned sewists. With straightforward controls and clear instructional manuals, even those new to sewing can quickly learn to navigate their functions. Moreover, these machines typically have reliable performance, reducing the number of headaches that can come with sewing irregularities, such as thread jams or fabric bunching.


  • Choosing the Right Walking Foot Sewing Machine


  • 3. Walking Foot A walking foot is an invaluable accessory for upholstery sewing. It helps in feeding multiple layers of fabric evenly through the machine, preventing puckering and ensuring that your seams are uniform.


  • What Makes a Heavy Duty Machine Different?

  • Chain stitch machines work by creating a looped stitch that interlocks with the fabric, creating a secure seam. This type of stitch is commonly used in denim jeans, t-shirts, and other heavy-duty clothing items. The machine pulls a thread from a spool, creates a loop with a hook mechanism, and then secures the loop with a set of feed dogs that move the fabric through the machine.
  • Another important factor to consider is the machine's stitch speed. A quilting machine with a fast stitch speed can help you finish your projects more quickly and efficiently. However, it is also important to consider the machine's stitch quality, as a machine that offers both speed and precision will provide the best results.

  • Mark, a craftsman specializing in leather goods, mentions, “The investment in a heavy-duty machine has paid off. I can work faster, and the stitch quality, even on thick leather, is impeccable.”

  • Proper tension is essential when sewing leather. Before starting, spend some time testing your machine’s tension settings on scrap leather pieces. A balanced tension will yield clean and even stitches. It is also advisable to use a longer stitch length (around 3.5 to 4 mm) when sewing leather to prevent the material from perforating too much, which can weaken its structure.


  • When considering the price of a bag closer machine, it is important to factor in the long-term benefits and savings that it can provide. Investing in a high-quality machine may initially cost more, but it can lead to significant cost savings in the long run. A reliable machine with advanced features can increase productivity, reduce downtime, and minimize maintenance costs.

  • The material of lock stitch sewing machine needles is another factor to consider. Most needles are made from high-quality steel, often coated with chrome or nickel to enhance durability and reduce friction. These coatings enable smoother sewing, especially when working with dense or heavy materials. Using the right needle material can significantly impact the lifespan of both the needle and the sewing machine, as well as reduce the likelihood of needle breakage, hence preventing potentially costly machine repairs.


  • Understanding Leather


  • The Chinese hand crank leather sewing machine is more than merely a tool; it symbolizes a rich history of craftsmanship, creativity, and dedication to quality. As appreciation for handmade and artisanal products continues to grow, these machines are likely to secure their place in the hearts of many creators. They stand as a bridge between the past and the future, allowing new generations to engage with traditional techniques while producing items that carry the weight of personal stories and craftsmanship. In a world racing toward automation, these charming machines remind us of the value of patience, skill, and human ingenuity in creating something truly beautiful.


  • Furthermore, automatic bag closing systems can help companies meet regulatory requirements and industry standards. By providing a consistent and reliable sealing method, these systems can ensure that products are packaged and sealed according to established guidelines, reducing the risk of non-compliance and potential fines.

  • A PP bag silai machine is specifically designed for sewing and stitching polypropylene bags, which are commonly used for packaging agricultural products, industrial materials, and consumer goods. These machines are engineered to handle various bag designs and sizes, making them an essential tool in factories that manufacture PP bags.


  • Understanding Bulk Bag Sewing Machines


  • Traditionally, sewing leather was done by skilled artisans using hand-operated tools. This method, while effective, was time-consuming and required a high level of expertise. With the advent of industrial sewing machines in the 20th century, the production process underwent a significant transformation. These machines are engineered to handle the unique characteristics of leather, which is heavier and more robust than other fabrics.


  • 2. Ballpoint Needles Ideal for sewing knits and stretch fabrics, these needles have a rounded tip that allows them to slip between the fibers without damaging them.


  • A serger, also known as an overlocking machine, is a specialized sewing machine that is used to create a professional finish on the edges of fabric. This machine is commonly used in the garment industry, as well as by home sewers who want to achieve a professional look in their sewing projects.
  • Additionally, a walking foot is a helpful feature to have when sewing leather and canvas. This type of foot ensures that the fabric moves smoothly through the machine, preventing any bunching or puckering that can occur with these thick materials. A walking foot can make a big difference in the quality of your finished projects.

  • 3. Brand Reputation Research and consider reputable brands known for their quality and reliability. Investing in a well-known brand may ensure better customer support and easier access to replacement parts.
